Abstract

Appareil de detection du tirage pour un tracteur agricole ou autre. Le tracteur est pourvu d'une fleche flexible s'etendant transversalement (18). Les extremites avant d'une paire de tiges d'assemblage de trait inferieures sont fixees sur les extremites exterieures de la fleche (18). La fleche (18) plie proportionnellement a la traction dans les tiges de connexion. La traction est detectee par l'intermediaire d'un dispositif a effet Hall (52) porte par un attelage (54). L'extremite avant de l'attelage (54) est montee de maniere pivotante sur une fleche fixe s'etendant transversalement (48) et la partie arriere de l'attelage recoit de maniere coulissante la fleche (18).Une tige d'assemblage (60) pivotant sur l'attelage (54) possede une partie extreme en contact avec la fleche (18) et son autre extremite est en contact avec une extremite d'une goupille (70) armee avec un ressort. L'autre extremite de la goupille porte un aimant permanent (78) en alignement axial avec le capteur (52). Lorsque la fleche s'incurve suite aux variations de la traction, l'aimant (78) se rapproche et s'eloigne du capteur (52) provoquant une variation de tension dans la ligne (98). En montant le capteur (52) de la maniere indiquee, l'effet de flexion verticale de la fleche de charge (18) est reduit de maniere considerable par rapport a la flexion horizontale.
